What Are QR Codes?
QR, or Quick Response, codes are two-dimensional barcodes that store data in a machine-readable format. Originally developed in Japan for tracking parts in the automotive industry, they have since evolved into a versatile tool for a wide range of applications.
Why Are QR Codes Useful?
QR codes are valuable for several reasons:
Convenience: QR codes provide a quick and efficient way to access information or websites without typing URLs or searching.
Versatility: They can store various types of data, including text, URLs, contact information, and even Wi-Fi network credentials.
Contactless: In an era where contactless interactions are essential, QR codes allow for touch-free access to services and information.
Marketing: Businesses use QR codes for marketing purposes, directing customers to websites, promotions, or product details.
How to Scan QR Codes on Android Devices:
Built-In Camera App: Many Android devices come with a built-in QR code scanner feature. Open your device's camera app and point it at the QR code. You'll typically see a pop-up notification with the option to open the linked content.
Google Lens: Google Lens, a visual search tool, can also scan QR codes. Open the Google Lens app or access it through Google Photos. Point your camera at the QR code, and Google Lens will recognize and provide relevant information or actions.
Third-Party Apps: Numerous QR code scanning apps are available on the Google Play Store. These apps often offer additional features, such as saving scanned codes or generating your QR codes.
Creative Applications of QR Codes:
